Some bud shots from last night, that canopy is getting thick all the way through the room. The JTR and BD shots were cropped less as there were some nice background colas in those pics :)

Those look awesome.
The jtr seems to be the key to a lot of killer looking crosses.

Cheers @torontoke, she was the mother of the original Blue Ripper cross and a fine specimen that's survived a lot of culls. The male from the F1's is killer too though, it picked up and is passing on the JTR frost genes to everything I hit with it. If you do any of your own crosses I have that male cloned (PM). The clone doesn't get culled until the next set is rooted in party cups, don't want to lose him, need him for back crosses and apparently for new crosses ;)

Day 32/50/65. Coming along nicely, fattening & frosting up. That Blue Ripper x Blue Dream P2 (bottom-center 1st pic) at day 65 is finally starting to mature, will go another week easy but starting to turn. Had to stake it, that main was leaning too far, bit of weight on it :)

For my Sunsystem tent I only cool it passively, using it as the intake
for my HPS tent which had a panisonic whisperline pulling air out,
but I still manage. The vertical bulb configuration has the effect of
directing less IR energy at the plants. My setup is simplistic tho.

Likewise. Groerr how do your leds yield on a watt to watt basis against the ss 315s? Would you recommend tastys panels I need to buy a couple 3x3s or build a 3x6 panel. Not sure how much id save by doing a diy with crees.

P.S. your garden is kicking ass!

Cheers @DesertGrow89 pretty happy with the 3590's and no issue recommending the Tasty bars, quiet and cool making it easier to maintain the environment. As far as weight, they're close but the COBs have produced my best weight for a control pheno I've run a couple of times under the COBs and had run many times under the LEC's, based on that looks like about 15-20%, that pheno had produced it's best at .7 oz./gal of medium under CMH and hit .86 oz./gal with the COBs. I also have a JTR in there right now that's produced .75 oz./gal at it's best run under CMH and is easily looking like a 3 oz. plant in a 3 gal container. So slightly better production and the quality is beyond anything I've run. This JTR pheno in there is the loudest it's ever been in 3+ years I've been running it. I don't think you can go wrong with the 3590's whether pre-built or DIY, I chose the pre-built just for time and there was a slight difference between the Tasty bars and DIY but not worth the time or effort for me.

If you go the COB root 30w/sq./ft. is plenty imo, I'm running them at 25w/sq./ft. in this run and the buds are dense all the way down.

That is awesome information. I've seen people (well, online...) pound their spaces with 60+w/sf, and others go as low as 25-30w/sf.... and I've seen great results from both! I haven't comprehensively gathered the rest of the picture: who is using soil vs. hydro, what nutes and how much, etc. -- and how far from the canopy are the lights hung. There are so many variables that its hard to convey what works and what doesn't just in terms of one element like w/sf.

Every time I lower my lights I get nute issues, so my hypothesis is that tons of light stresses the plants, and unless the grower can match nutes to that extra demand, it works against the plants. In my 2x4 I'm running 8 3070's at about 50w each for 50w/sf, but I have them about 26" off the canopy (which is twice as far as I've seen others go). With no lenses or reflectors, if I had dimmers on them all I could probably dim them and drop them significantly and run the tent cooler. Next rebuild maybe.

In my 3x3 as I mentioned I'm experimenting with an HID/COB mix, so I'm not sure how to calculate the w/sf. Your method of oz/per gallon of medium is an interesting constant in the comparisons, especially as we compare different light platforms.

Lookin great as usual!

In my initial run with the cobs on a brand new strain.... i have to say the same as @Humanrob . It seems the cob intensity has a very profound effect on nute uptake. It'll take a couple runs to figure it out, but i too am sold on cobs after this one run.

What is obvious for the next run on the same strain is that 12" is too close for Tastys 3590s at full power for my feeding regimen. So adjustments will be made maybe back off the lights a bit and up the nutes some. See what happens ...

Anyway... love your garden and pics!
